CASH REGISTER Filed Sept. 7, 1935 3 Sheets-Sheet 3 Patented Feb. 24, 1942 UNITED STATES PATENT OFFICE CASH REGISTER William Leonard Paden, Dayton, Ohio Application September 7, 1935, Serial No. 39,582

32 Claims.

This invention relates to cash registers and indicators, and more particularly to a register mechanism of the lever operated type having amount determining means for setting up' the sum to be registered in advance of the actuation of the registering mechanism.

The present register construction embodie a succession of banks or units of similar construction arranged side by side, and corresponding to cents, dimes, dollars, tens of dollars, and hundreds of dollars respectively, only one of which is illustrated. Each unit or bank of mechanism includes a dial operated setting element movable through different ranges of adjustment according to the value to be set up and an associated actuating lever movable through a full stroke motion at each operation for registering the amount determined by the dial setting, together with gear segments movable in unison with the actuating lever through distances proportionate to the amount determined by the dial setting for correspondingly actuating accumulator and indicator devices. A variable stop device for arresting the corresponding indicator in predetermined position is adjusted automatically by op,- eration of the mechanism as is also means for connecting and disconnecting the accumulator devices and preventing overthrow thereof.

While one of the more serious objections to lever operated register mechanisms has been the excessive manual effort and power required for actuation of the register, which power requirements usually increase with the registry of sums embodying higher digits and consequent longer movements of the register mechanism elements, one of the important features of the present construction is the provision of counterbalancing means and automatic variation of differential tension upon the actuating parts during movement whereby the resistance to operation is minimized and the tension is equalized throughout the full stroke operation.

The object of the invention is to improve the construction as well as the means and mode of operation of cash register mechanism, whereby it may not only be economically manufactured, but will be more efficient in use, of greater accuracy in operation, easily operated, and unlikely to get out of repair.

A further object of the invention is to provide a flexible dial type setting mechanism, whereby the amount to be registered may be predetermined and any error in setting up the amount readily corrected before registry thereof.

A further and important object of the invention is to provide automatic tension equalizing and counterbalancing means which will automatically compensate for variation of power required for registering different sums.

A further object of the invention is to provide compensating means whereby the expenditure of effort necessary for actuation of the mechanism is reduced to minimum.

A further object of the invention is to provide amount setting and register actuating means for each bank or unit of mechanism, which may be actuated by a single continuous movement, or may be separately operated at the will of the operator.

A further object of the invention is to provide a plurality of actuating devices for the register mechanism, any one of which may be operated to register a sum set up collectively in the corresponding bank and other banks of mechanism.

A further object of the invention is to enable the registration of a previously predetermined sum by actuation of any one of several operating devices.

A further object of the invention is to enable the amount to be registered to be preindicated by setting up the denominational figures of the sum in a straight line normal reading relation.

Further objects of the invention are to provide improved indicator arresting means to prevent overthrow thereof, and to provide improved means for controlling the connection and disconnection of accumulator mechanism at predetermined times in the cycle of operation.

A further object is to provide a cash register mechanism of compact construction whereby a register of comparatively large capacity may be made to occupy a relatively small space.

A further object of the invention is to provide a mechanism of which a relatively large proportion of the parts may comprise stampings and other economically manufactured parts whereby the costs of manufacture may be minimized.

A further object of the invention is to provide a cash register mechanism having the meritorious features and the advantageous structural characteristics herein mentioned.

A further object of the invention is to provide a mechanism whereby the amount can be set up and registered in one continuous movement.

With the above primary and other incidental objects in view, as will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents, as hereinafter described and set forth in the claims.

Figs. 7, 8 and 9 are detail views of the operating levers and their terminal extensions.

Like parts are indicated by similar characters of reference throughout the several views.

The register mechanism includes a succession of identical units or banks of mechanism, assembled side by side upon a common main shaft and operable to register denominational sums, the actuating elements of which, however, are interconnected for unison operation through the main shaft.

Referring to the drawings, l is the end plate of the machine frame, two of which are interconnected in spaced relation by interconnecting frame rods and shafts with succeeding denominational banks or units of mechanism pertaining to cents, dimes, dollars, tens and hundreds of dollars, interposed side by side therebetween. Mounted in the end plates l and extending centrally through the machine is the main shaft 2 upon which the amount determining and operating parts are mounted.

Pivotally mounted upon the main shaft 2 for free oscillatory movement relative thereto is the setting lever comprising a pair of parallel interconnected spaced arms 3 carrying at their forward free ends an arcuate dial head 4 having in its forward face a succession of finger holes 5 corresponding to the digits zero to nine and so numbered. At its rear side, the dial head 4 is provided with a succession of notches 6, one for each position of adjustment and corresponding to the numbered finger holes 0 to 9.

Loosely journalled also upon the main shaft 2 is the actuating lever which comprises a pair of parallel spaced arms 1 extending exteriorly of the arms 3 of the setting lever, and interconnected at their forward ends where they carry a dependent arcuate head 8. Intermediate the parallel spaced arms 3 and l of the setting and actuating levers which are loosely journalled upon the main shaft 2, is a coupler arm 8 which is fixedly secured upon the main shaft 2 by pinning as at IE1, or otherwise, and which carries at its forward free end an upwardly extending arcuate arm or head I l.

Loosely journalled upon the main shaft 2, intermediat the arms 3 and I of the setting and actuating levers and intermediate such arms and the coupler arm 9, is a pair of oscillatory gear segments l2 and (3, one of which pertains to the accumulator mechanism and the other to the indicator. These gear segments are provided with radially extending arms l4 extending into the path of a contact lip or lug l5 upon one of the setting lever arms 3, which, upon continued movement of the setting arm under influence of the actuating lever as hereinafter described, will engage the gear segment arms M to oscillate the gear segments 12 and I3 through a movement corresponding to the amounts set up by the initial adjustment.

Mounted upon transverse frame rods i6 connecting th end plates l and extending in dependent relation between the parallel spaced arms 3 and I of the setting and actuating lever is an arcuate finger ll concentric with the cen ter of oscillation of the several parts and the main shaft 2. Pivotally mounted at 18 upon a dependent portion of the actuating lever I and adjacent to its arcuate head 8 is a locking arm 19, to the lower end of which is connected an actuating spring 20 which tends to oscillate the end of the locking arm I9 above the pivot l8 outwardly. The locking arm I9 is normally held against such movement under influence of the retracting spring 20 by a finger 2i abutting upon a stop lug 22 projecting from a depressible slide 23 mounted upon the arcuate head 8 of the actuating lever and having at its upper end a finger contact pallet 24 by which the slide may be depressed against the resistance of a retracting spring 230. to release the locking arm l9. At its upper end, the arm 19 carries a stud 25 normally positioned above the upper end of the stationary arcuate arm l1, and by its engagement therewith serving to lock the actuating lever l in its elevated normal or home position.

The head or arm ll of the coupler arm 8 is provided with a notch 26 opposite the stud 25 of the locking lever [9. This notch 26 in the coupler arm is normally positioned opposite an unnctched part of the setting lever head 4 below the zero position. Upon oscillation of the setting lever 3 by depression of the dial head t, the notch 6 corresponding to any one of the selected digits may be brought into registry with the notch 26 of the coupler arm. In setting up any sum to be registered, the operator by setting his finger in the dial opening 5 corresponding to the desired digit draws the setting lever read t and with it the arms 3 downwardly about the journal connection upon the main shaft 2 until such movement of the setting lever is arrested by the engagement of the operators finger with the contact pal-let 24 of the slide 23.

The depression of the slide under impact of the operators finger with the pallet 24 withdraws the stop 22 from the path of the locking arm finger 2!, allowing the finger to oscillate under the influence of the spring 20 to shift the locking stud 25 off the end of the arcuate finger ll, thereby unlocking the actuating lever and simultaneously moving the stud 25 into the notch 26 of the head or arm ll of the coupler arm 9 and into whichever one of the notches 6 of the head 4 which has been registered with the notch 28 by the movement of the setting lever.

The oscillatory movement of the locking lever 49 by movement of the stud 25 from over the end of the concentric arcuate arm ll into the registering notches B and 26 interlocks the actuating lever I and setting lever 3 with the coupler arm 9 for unison movement. The initial setting movement of the setting lever 3 has moved the contact ear or lug l5 a predetermined distance toward the gear sector arms I4, corresponding to the selected digits. At this stage the parts will have been moved from the position shown in Fig. 1 to that shown in Fig. 3, wherein the setting lever 3 will be locked in a depressed position in its relation with the actuating lever 'I and coupler arm 9 which still remain in their normal positions. However, prior to movement of the actuating lever from its home position, the setting lever and dial head may be readjusted to correct any error in the initial setting.

The notches 6, in the inner face of the dial head 4, are of slightly rounded or cam shape, and upon slight upward effort being applied to the dial head 4, the detent stud 25 may be cammed outof any one of these notches 5, thereby permitting readjustment of the setting lever. In lieu of such movement, the pallet 24 may be manually elevated causing the lug 22 to move upward, and by reason of the spacing between the end of the finger 2| and the point of contact of the pin 22 on the actuating lever 1, and the arcuate slot 2|, camming the finger 2| rearward to oscillate the lever I9 and withdraw the stud 25 thereby permitting the setting lever to be retracted by spring tension. More specifically, members |92| form a bell crank, and when force is applied to one arm of a bell crank it will rotate so as to bring the direction of the force application into line with the reacting force which passes through the pivot.

The line of force and the line of reaction must coincide in order that the bell crank be stable, and as the line of force cannot coincide with the line of reaction the bell crank |92| rotates until 2| clears 22 which releases the force from the finger. The end of the finger 2| of the arm l9 which passes over the stop lug 22 when the pallet is depressed is, if desired, slightly inclined or cammed sufficiently that manual upward pressure upon the pallet will assist in the retraction of the finger 2| and with it the stud 25. However, when the actuating lever has been moved from its home or normal position by a continued downward pressure upon the finger pallet and 29, in the setting lever and coupler arm respectively, extend in transverse or intersecting relation, and receive at their point of intersection a roller stud 38 in the lower end of an indicator stop bar 3|. The roller stud 38 engages in both of the intersecting slots 28 and 29. As the oscillatory movement of the setting lever 3 relative to the coupler arm 9 is effected, the point of intersection of the cam slots 28 and 29 is varied toward and from the center of oscillation. The roller stud is thus correspondingly shifted toward and from the main shaft 2 whereby, upon unison movement of the parts under influence of the actuating lever 1, a greater or less longitudinal movement is transmitted to the indicator stop bar 3| according to the degree of initial relative adjustment of the setting lever which in turn is dependent upon the selected digit of the dial head 4.

The stop bar 3| in turn positively arrests the indicator in position corresponding to the selected digit and prevents overthrow thereof.

There are two levers, to wit, the setting lever and the actuating lever, the setting lever being movable relatively to the actuating lever different distances in accordance with the amount 1 to 9 to be set up, and which movement of the setting lever does not effect any adjustments of the other mechanism. At the end of this preliminary independent movement of the setting 24 thereby carrying the locking stud 25 down- I wardly past the upper end of the arcuate stationary arm H, the stud 25 will be held in the registering notches 5 and 26 of the dial head 4 and coupler arm 9 respectively by the arcuate bar l1, and will be prevented from escape from such registering notches during the entire downward and return movement of the parts until the stud 25 is again elevated above the upper end of the arcuate bar I! in the normal returned position of the actuating lever. During the time the operated parts are away from normal position, the actuating levers pertaining to unused denominational banks are locked in home position by the arms I of the corresponding coupler levers, which, moving at every operation, lock the detent studs 25 of the unused bank over the top of the stationary bar One arm 3 of the setting lever is provided with a dependent portion 21 to accommodate an angular cam slot 28 therein, the dependent portion of which is concentric with the center of oscillation of main shaft 2, and the radial portion of which is slightly curved or arcuate. The coupler arm 9 is provided with a coacting arcuate cam slot 29 curved in reverse direction to that of the radial portion of the slot 28. The cam slots 28 lever, it is locked to the actuating lever for additional movement therewith.

The actuating lever has a constant range of movement and moves through its full stroke until arrested by the stop rod 55 at each operation. This movement of the actuating lever is sufiicient to carry the registering mechanism through a range ample to register 9, if the setting lever has previously been set for a 9 registration, plus suflicient movement to lock the accumulator in operative position and unlock the indicator. Such full stroke movement of the actuating lever is correlated with the idle movement between the contacts Ma and |5 by initial adjustment of the setting lever, which is capable of a nine-step movement independently of the actuating lever and also movement in unison therewith.

Assuming the setting lever is initially moved independently of the actuating lever a distance of three steps, this causes the contact l5 to approach the head I 4a a distance of three steps. At the end of this initial three-step movement the setting lever is locked to the actuating lever and both levers are moved in unison through the additional nine-step range of the operating lever. Thus, the interlocked levers will move idly through six steps before the contacts Ma and I5 engage and thereafter will move an additional three steps during completion of the full stroke movement of the actuating lever, carrying with it the gear segment and actuating the accumulator to add 3 thereon. The setting lever will have initially moved through a three-step movement independently of the actuating lever to set the contact I5 in relation to the contact Ma and will then have moved nine steps more in unison with the actuating lever, of which six steps are idle, to bring the contacts Ma and I5 together. During the final three steps of movement, the gear segments l2 and I3 will be carried along in unison to actuate the accumulator and set the indicator. It will be noted that the gear segments I2 and |3 or the contact |4a are not at any time interlocked with the setting or the actuating lever.

The initial movement of the setting lever independently of the actuating lever is limited by the engagement of the operators finger with the operating lever whereupon the levers are interlocked for further unison movement. That is, whatever the extent of such independent movement may be, it is limited by the engagement of the operators finger with the actuating lever, and the interlocking of the levers occurs at such limit of independent movement.

Inasmuch as the setting lever 3 initially moves independently of the actuating lever and coupler arm in order to set up the amount to be registered and is held in its adjusted relation by the engagement of the detent stud 25 in one of the notches 8 corresponding to the selected digit, the dials pertaining to different denominational banks may be operated in succession or together to correspondingly adjust the setting levers 3 of the different banks or units to set up a sum containing cents, dimes, dollars, tens of dollars, and hundreds of dollars as may be desired, and before the actuating lever is operated to register such sum the setting levers may be readjusted to correct any error. However, when such sum has been set up, the setting levers and actuating levers of the different banks or units have been interlocked with the corresponding coupling arms for unison movement. In the event that any one or more setting levers pertaining to different banks of mechanism have not been operated, the levers of such bank will not be interlocked with the corresponding coupling arm since the stud 25 in such event will be held out of engagement with the notch 26 of the coupling lever by the unnotched portion of the head 4 opposite the zero position. Therefore, the coupling arm 9 of any such unoperated bank or unit will be free to move downwardly with the oscillation of the shaft 2 independently of the setting lever 3 and actuating lever l which will remain in their normal elevated or home position during subsequent operation of the mechanism.

After the dials and setting levers pertaining to the selected banks of mechanism have been adjusted to set up the desired sum to be registered, it is quite immaterial which actuating lever shall be depressed to register the amount. Since the actuating lever 1 of each bank of mechanism or" which the dial 4 and setting lever 3 have been adjusted is interlocked with the corresponding coupling arm 9 of such bank by the engagement of the detent stud 25 and since all of the coupling arms 9 are pinned or otherwise fixedly secured to the main shaft 2, all of such actuating levers T will move in unison.

Fixedly connected to the main shaft 2 at one end thereof is a segment 32 having therein a series of notches 33 engaged by a full stroke pawl 34 which is reversible only beyond the limit of the notched portion of the segment. The engagement of the pawl 34 with the notched portion 33 of the segment 32 compels a full movement of the actuating mechanism, first in one direction and then in the other. During the downward movement of the interlocked setting and actuating levers and coupling arm 9, the contact ear or lug upon the setting lever arm 3 will engage with the arms M of the respective gear segments l2 and I3, and will carry such gear segments about the shaft 2 in unison with the movement of the interlocked levers.

The contact lug [5 upon the setting lever 3 will move idly a greater or less distance before engaging the gear segment arms |4 according to the position to which the setting lever has been initially adjusted. After its engagement with the gear segment arms l4 it will oscillate the gear segments l2 and I3 in unison with the movement of the lever throughout the remainder of its travel range a distance proportionate to the initial setting of the lever 3 and dial head 4. The gear segment |3 intermeshes with a gear segment 36 journalled upon a transverse frame rod 31 and having an opposite toothed portion 36a intermeshing with the gear pinion 38 connected with an indicator wheel 39. The gear segment 36 has therein a concentric slot 40 in which engages a stud 4| carried by the upper end of the indicator stop bar 3|. Normally the stud 4| engages the upper end of the concentric slot 40 in the gear segment 36.

As the setting lever 3 is initially adjusted relative to the coupling arm 9, thereby varying the point of intersection of the cam slots 28 and 29, the position of the upper end of the indicator stop bar 3| is not changed but the stop bar will in effect swing slightly about its pivotal stud 4| at the upper end of the slot 4|) as the roller stud 39 changes its position toward or from the main shaft 2 as the point of intersection of the cam slots 28 and 29 is varied by the adjustment of the setting lever.

Due to such shifting of the relation of the roller stud 30 to the center of oscillation a greater or less movement is transmitted to the indicator stop bar 3| by the uniform full stroke movement of the bars at each operation. That is to say, if the setting lever has been adjusted to the 1 position, the roller stud 30 will be spaced at greater distance from the center of oscillation and hence the bar 3| will be given a greater degree of movement than if the setting lever has been adjusted to the 9 position, which causes the roller stud 30 to be adjusted close to the opposite ends of the intersecting cam slots 28 and 29 and hence close to the center of oscillation where the full stroke movement of the actuating parts will transmit but a relatively short movement to the indicator stop bar 3|.

This adjustment of the indicator stop 3|, of course, occurs during the initial adjustment of the setting lever by which the sum to be registered is set up before the register mechanism is actuated. Upon depression of the actuating lever 1 which has been interlocked with the setting lever 3 and coupling arm 9 as before described, the indicator stop arm 3| is drawn downwardly, and the gear segments l3 and 36 are actuated to rotate the indicator through proportionate degrees to indicate the amount set up on that particular bank.

During such movement of the indicator, the oscillation of the intermediate gear sector 35 will have brought the opposite end of the concentric slot 49 into engagement with the stud ll in the end of the stop bar 3|, thereby arresting the segment 36 and with it the indicator 39 actuated thereby. The indicator 39 is held in its adjusted position by a spring detent finger 42 engaging with a star-wheel or notched disc 43 connected to and rotating in unison with the indicator wheel 39.

The spring detent finger 42 and an oscillatory lever 44 are carried by shaft 45 journalled in the end plates one end of which is connected with a retracting spring 46. The opposite end of the rock-lever 44 has a pin and slot connection 41 with a bell crank lever 48 mounted upon a transverse frame rod 49. At its free end, the

bell crank lever 48 carries a stud 50 cooperating with a cam dog pivoted at 52 to one side of the segment 32 and having a limited range of oscillatory movement about its pivotal connection against the tension of a retracting spring 53. The segment 32 being pinned or otherwise fixedly secured to the main shaft 2 and oscillating in unison with the depression of any one of a series of actuating levers by its initial movement forces the inclined end of the cam dog 5| against the stud 50, causing the bell crank lever 48 to be oscillated and thereby transmit motion to the lever 44 against the tension of the spring 46 to withdraw the spring detent arm 42 from engagement with the star wheel 43, thereby permitting the indicator wheel 39 and associated gear segments 36 and I3 to return to normal preparatory to being reset by the continued movement of the actuating mechanism.

During the continued movement of the actuating levers and the segment 32, the stud '50 of the bell crank lever 48 will ride over the top of cam dog 5| holding the locking detent 42 out of engagement with the star wheel 43 during the downward or operating stroke of the actuating lever. At the limit of the movement of the segment 32, the pin 50 will pass beyond the pivotal end of the cam dog 5|, and during the return oscillation of the segment, the stud 50 will pass idly beneath the cam dog, raising the latter against the tension of its retracting spring 53 which, as the parts return to their normal positions at the completion of the operation, again positions the cam dog 5| for operative engagement with the stud 50 at the next operation.

The segment 32 is limited in its oscillatory movement by engagement with a transverse frame rod 54 and at the same time the head 8 of the actuating lever engages with a transverse frame rod 55 which also serves as a limiting stop. During the return movement of the segment 32, as before described, the detent arm 42 engaging with the notched disc or star wheel 43 holds the indicator wheel 39 in its operated position. The actuating gear segments l3 and 36, by which motion is transmitted to the indicator wheel, are also held in their advance or operated positions until the next cycle of operation of the mechanism when the action of the cam dog 5| in elevating the bell crank lever 48 releases the indicator and related gear segments l3 and 36 for resetting. The oscillatory movement of the parts under influence of the actuating lever 1 also effects the interconnection of the accumulator devices with their actuating segment I2.

The accumulator mechanism indicated at is carried upon a swinging frame 6| pivoted at 62 to a stationary portion of the main frame of the register. The accumulator devices, which may be of conventional form and hence have not been shown in detail, are provided with accumulator gears 63 moved into and out of intermeshing engagement with the gear sectors l2 by which the accumulator gears 63 are rotated distances proportionate to the digits set up in the corresponding banks.

The accumulator mechanism is lowered into operative relation with the actuating gear segments |2 during the movement of the parts in one direction and elevated therefrom during the return motion by means of a double cam lever 64 carried by the oscillatory segment 32 and pivoted to a supporting finger 64 thereon at 65 within an irregular opening 66 in the segment. The cam lever 64 is movable about its pivotal connection against the tension of a retracting spring 61. A stud 68 upon the swinging counter frame 6| projects within the opening 66 into engagement with the oscillatory cam member 64. In the normal position of the parts, this stud 68 is positioned at the forward end of the cam member 64, as is shown in Fig. 1.

Upon the initial actuating movement of the segment 32, the stud 68 is cammed downwardly and passes beneath the cam member 64 as the segment oscillates. This downward movement of the stud 68 carries with it the frame 6|, drawing the accumulator gears 63 into intermeshing engagement with the actuating gear segments l2. At the limit of the actuating movement of the parts, the stud 68 will have passed beyond the rear end of the cam member 64 and the cam member will have been passed into the return path of the stud by its retracting spring 61. Thereupon the return oscillation of the sector 32 will cause the stud 68 to climb upwardly and pass over the top of the cam member 64, lifting the accumulator frame 6| and disengaging the accumulator gears from the actuating segments l2 during the return movement of the parts. The stud 68 finally comes to rest in the notch 68 to maintain the accumulator mechanism in up position pending a subsequent cycle of operations as just described.

The accumulator device being lifted out of engagement with the actuating gear segment l2, the latter returns to its normal or home position with the return under spring influence of the remainder of the actuating mechanism. The indicator wheel 39 being held in its operated position by the detent arm 42, the actuating gear segment l3 therefor remains in its operated position and does not return until the initiation of the succeeding cycle of operation.

The several operated parts are returned to normal by retracting springs 13 and 18 associated with the setting and actuating levers respectively and with the coupling arms and thus with actuating segments I2 and I3 for the indicator and accumulator devices. The locking stud 25 is held in engagement with the registering notches 6 and 26 in the dial head and coupler arm respectively until the actuating lever 1 has reached its normal or home position, and the locking stud 25 has been elevated above the upper end of the concentric stationary finger whereupon the stud 25 will be cammed out of the registering notches by the continuing upward movement of the setting lever and will be forced over the end of the finger by the unnotched portion of the dial head belowthe notches 6 and opposite the zero position where it is locked by the pallet 24 to hold the actuating lever 1 in its retracted position. During this return movement, the stud 50 of the bell crank lever 48 will have traveled beneath the cam dog 5| and assumed its normal position at the forward end thereof while the stud 68 of the accumulator frame 6| will have traveled over the top of the double pivoted cam 64, and assumed its normal position at the forward end thereof, as shown in Fig. 1.

The retracting springs for the several operative parts are mounted for automatic equalizing adjustment toward and from the center of oscillation of the spring actuated member whereby, as the degree of movement increases which would normally increase the spring tension, the spring moves toward the center of oscillation a proportionate distance. Briefly stated, the retracting springs which are of the helical tension type, are

slidingly connected at their opposite ends with spaced guides which change their relative angula-r relation in unison with the movement of the part to be retracted, the sliding adjustment of the spring upon its guide effecting a progressive change of leverage by which, as the tension of the spring increases, the leverage through which it reacts is shortened and vice versa. This automatic equalization of the spring tension against the yielding resistance of which the various parts are operable is considered an important and highly desirable feature of the present construction.

Referring to the drawings, the actuating levers I are each provided with slotted arcuate arms 10 which move in unison therewith to different approximately radial positions about the center of oscillation or main shaft 2.

Mounted upon transverse frame rods H in the bottom of the main frame is a series of slotted guide bars 72. Connecting the oscillatory guide arms 73 and the corresponding stationary guide bars 12 in the main frame of the machine is a series of helical tension retracting springs 13.

The springs 13 are provided at their opposite ends with heads 14, preferably equipped with small rollers 15 engaging within the guide slots of the arms 19 and bars 12 for to and fro shifting motion therein.

As the actuating lever l is oscillated, the arms 70 moving in unison therewith vary their angular relation with the relatively straight guide bars 12. The slots in the arms 10 are disposed upon a curvature such that the progressively changing angular relation of the curved slots will cause a shifting movement of the spring head 14 relative thereto under constant control. That is to say, the roller bearing head M will not rush suddenly from one end to the other of the guide slots, but will gradually move therein as the angularity of succeeding portions of the curved slot change with relation to the straight guide bars '12. Thus at the beginning of the movement of the actuating lever l the spring heads 14 will be positioned at the extreme outer ends of the slotted arms H! where the tension of the retracting springs 13 will be relaxed, but where the effective leverage of the arms 10 will be greatest.

As the lever 7 moves downwardly in its actuating stroke, the upward oscillation of the opposite arms '10 will tend to increase the tension of the retracting springs 13, but coincident therewith the spring will move bodily inwardly upon the arm '50 toward the center of oscillation, thereby correspondingly decreasing the effective leverage, until at the limit of the downward movement of the lever, the spring heads 14 will occupy the position at the inner end of the slotted lever Ii! where the effective leverage is the least but in such position the spring will be under its maximum tension. Thus a converse ratio of spring tension to effective leverage is maintained whereby the resistance offered by the retracting spring will be equalized throughout the actuating movement by the bodily movement of the springs through successively parallel planes. By such construction the retracting springs I3 may be so tensioned as to balance the operating parts in any position of adjustment. However, the springs are tensioned slightly beyond the balance point, whereby they will have suflicient power to return the operated parts, but due to the automatic equalization of the tension-leverage ratio, the resistance to movement will be minimum and equal throughout the entire range of operation. As before stated, the setting lever 3 and dial head 4 are movable relative to the actuating lever 1 and then both levers are movable in unison with each other and with the coupling lever. This latter movement is against the tension of the springs 13, However, the setting lever is provided with a further tensioning spring controlling its movement relative to the actuating lever.

To this end, the setting lever is provided with a slotted arm 16 integral with the setting lever arm 3 and moving in unison therewith. The actuating lever l is provided with a dependent slotted guide arm 11. The guide arm 11 is provided with a straight slot therein and corresponds in function and effect to the straight guide bars T2 in the bottom of the frame.

The setting lever arm 16 is provided with an arcuate slot therein and this arm corresponds in function and efiect to the arms 10 before described. Interconnecting the guide arm 16 of the setting lever with the guide arms 11 of the actuating lever is a retracting spring 18 having at each end sliding heads 19 provided with antifriction rollers 83 engageable within and movable to and fro in the guide slots of the respective arms 15 and 11.

When the setting lever 3 is in its normal or home position and the retracting spring 18 is relaxed, the heads 19 occupy the outer ends of the slotted arms 18 and 11, as shown in Fig. 1. As the setting lever is depressed relative to the actuating lever, the angular relation of the arms '16 and 11 being correspondingly changed, the retracting spring being placed under increased tension shifts its position along said arms toward the center of oscillation, thereby decreasing the effective leverage of the arm 16 upon the retracting spring as the tension thereof is increased. Such shifted position of the spring is illustrated in Fig. 4, wherein the retracting spring pertaining to the setting lever is shown in a mid-position since the setting lever has not been adjusted to the full limit of its range of movement relative to the setting lever, while in the same figure the retracting spring 13, pertaining to the actuating lever, is shown at the point of maximum tension and minimum leverage since the actuating lever is shown in Fig. 4 at the limit of its range of movement. By such shifting movement of the retracting spring, the resistance of the setting lever to a movement to register the digit 9 is no greater than that to register digits 1 or 2.

Likewise, during the registering operation the resistance to the depression of the actuating lever 10 is no greater as it approaches the limit of its range of movement than at the beginning of such movement. This equalization of resistance to the movement of the operated parts affords a practical solution for a problem which has long rendered the operation of such mechanism objectionable.

As before described, the indicator, and its actuating segments remain from one operation until the succeeding operation in their adjusted positions in which they have been positively arrested by the stop bar 3!. It is not necessary that they be returned to zero preparatory to resetting, unless the corresponding bank of mechanism is not employed. In such case the withdrawal of the detent 42 from the star wheel 43 will permit the segments and indicator to be retracted to zero by the segment retracting spring corresponding to the spring 13. If a lower number is to be registered in such bank the segments and indicator return under such spring tension until the setting lever and stop link are intercepted and the parts arrested thereby in the new position. If a higher number is to be registered the indicator and control segments are picked up by the operating parts and moved directly to the new higher setting.

The arm I4 of the accumulator segment I2 carries a lug or ear Ila which overhangs the arm I4 of the indicator segment I3. Hence the positive arrest of the indicator segment in its operated position serves also to arrest the accumulator segment, and prevents overthrow. The stop bar 3| is thus indirectly common to both the indicator and accumulator devices.

It is through the overhanging ear or lug I la that the motion imparted to the accumulator segment by the setting lever lug I5 is transmitted to the indicator segment. As the parts approach the limit of their movement at the end of each setting operation, the indicator segment I3 and accumulator segment I2 will be traveling in unison with the lug I4a of the accumulator segment arm I4 in overhanging engagement with the arm ll of the indicator segment and urging it through like motion. The accumulator segment however returns idly to normal under influence of the spring I3 which is effective on the coupling lever 9 after each setting operation, leaving the indicator segment in its operated position.

Upon the release of the actuating lever at the limit of its downward movement, the actuated parts are automatically returned to normal or home position by the action of the retracting springs. At the limit of such return movement the actuating lever I will impinge upon the frame rods I6 which form stops for the setting and actuating levers in their home position. The setting lever 3 having been initially advanced relative to the actuating lever I and locked in such relation by the detent stud 25 held in engagement by the arcuate finger I1, will return in the same relation in unison with the actuating lever 1 until the latter abuts the frame rods I6 and comes to a sudden stop. The detent stud 25 will then have been carried beyond the end of the locking finger I! and will be held in the digit notch only by the spring 20. The retractive acclined side thereof thereby permitting the settingv lever to continue its return movement until it too is arrested by contact with the frame rods IS. The retraction of the detent stud 25 by oscillation of the arm I9 against the tension of the spring likewise retracts the finger 2| out of engagement with the lug 22 on the depressible slide 23, thereby releasing the finger contact pallet 24. Thus the parts are all returned to normal preparatory to the succeeding operation.

To insure positive release of the setting lever 3 upon the return of th actuating lever I to normal position and permit the further return of the setting lever 3 to its zero position, the guide finger I! may be diagonally divided as is shown in Fig. 6. The upper portion I'Ia thereof is pivoted for swinging movement into the path of the stud 25 under influence of a retracting spring IIb. During the descent of the interlocked levers the stud 25, passing through its arcuate path in close conformity with the convex margin of the fixed guide finger I1, depresses the upper pivotal portion IIa against the resistance of its spring I'Ib (Fig. 6) into alignment with the continuing stationary portion of the finger I1, and is thereby held in latching engagement with the several levers locking the setting and actuating levers to the coupling lever for unison motion. However as the actuating and coupling levers approach the limit of their return movement, the free end of the pivoted portion Ila having been projected by the spring Ilb into the return path of the stud 25 is engaged thereby. The stud 25 is directed inwardly between the pivotal and stationary portions I la and I1 and caused to pass to the rear of the former, which thereby cams the stud 25 out of the notch 6 of the setting lever head 4 and the notch 26 of the coupling lever head II in registry therewith. Such retraction of the stud 25 releases the setting lever which may then continue its return movement to normal after the actuating lever and coupling lever have come to rest. The stud 25 in its final position overhangs the upper end of the portion He, thus locking the actuating lever in its retracted position, but' leaving the coupling lever free for independent oscillation until the setting lever is again operated and the pallet 24 again depressed by the operators finger at the limit of the setting lever motion.

The automatic shifting of the tension springs not only tends to equalize the resistance of the operated part by change of effective leverage in approximate proportion to the degree of movement, but it also governs the return motion, preventing a too rapid action. At the initiation of the return motion the action of the spring is upon a relatively short radius or short leverage which prevents a sudden action, but as the return movement progresses the effective leverage likewise increases. It is quite possible by tensioning the spring to cause the operated part to remain in balanced relation in any position of intermediate adjustment to which it may be moved. In practice the tension is adjusted but a slight degree beyond such balancing tension whereby the overbalancing influence of the spring will be comparatively little to be overcome by manual effort but will be substantially uniform throughout the entire range of movement.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.
